With the help of Nuku's auto-translator, we've imported over the clockwork foxes and the margay from the multi-player game.  I've spruced them up and everything, so they're ready to play with the players.
Clockwork Foxes: These foxes come in guy and girl varieties randomly, though you'll only get one or the other if you ban a group.  They'll switch you to the opposite gender unless you have a Male/Female pref set.
Margays: Just be aware, these new kitties are out for some particularly kinky, UB fun.  You have been warned. :)
Update 2/21:
Killer Whale: The Killer Whale has been ported over as well.
Wiki: A bunch more content has  been added to the single-player Wiki, with all the monsters put in and  at least some rough work on the locations.
Update 2/22:
Cerberus: The Cerberus has been adapted from the multi-player version and is now live.  Again, I get an unexpected surprise trait from a ported creature, this time a tail cock.  That's okay though, I have a little more experience with those. :)
